Abstract:The prospect of fast and affordable on-demand service delivery over the Internet proceeds from the very notion of Cloud Computing. For service providers, the ability to afford those benefits to the user is contingent on attaining rapid elasticity in service design and implementation, which is a very open research goal as yet. With a view to this challenge, this paper draws a trajectory that, starting from a better understanding of the principal service design features, relates them to the microservice architectural style and its implications on elastic scalability, most notably dynamic orchestration, and concludes reviewing how well state-of-the-art technology fares for their implementation.
